AbstractEpidemiologic studies on health effects of air pollution usually rely on time-series of ambient monitoring data or on spatially modelled levels. Little is known how well these estimate residential outdoor and indoor levels. We investigated the agreement of measured residential black carbon (BC) levels outdoors and indoors with fixed-site monitoring data and with levels calculated using a Gaussian dispersion model. One-week residential outdoor and indoor BC measurements were conducted for 15 families living in central Stockholm. Time-series from urban background and street-level monitors were compared to these measurements. The observed weekly concentrations were also standardized to reflect annual averages, using urban background levels, and compared spatially to long-term levels as estimated by dispersion modelling. Weekly average outdoor BC level was 472 ng/m3(range 261–797 ng/m3). The corresponding fixed-site urban background and street levels were 313 and 1039 ng/m3, respectively. Urban background variation explained 50% of the temporal variation in residential outdoor levels averaged over 24 h. Modelled residential long-term outdoor levels were on average comparable with the standardized measured home outdoor levels, and explained 49% of the spatial variability. The median indoor/outdoor ratio across all addresses was 0.79, with no difference between day and night time. Common exposure estimation approaches in the epidemiology of health effects related to BC displayed high validity for residencies in central Stockholm. Urban background monitored levels explained half of the outdoor day-to-day variability at residential addresses. Long-term dispersion modelling explained half of the spatial differences in outdoor levels. Indoor BC concentrations tended to be somewhat lower than outdoor levels.

The world's challenges of climate change, damage to ecosystems, and social and health inequalities require changes in human behaviours at every level of organisation, among governments, business, communities, and individuals. An important question is how behaviour change can be enabled and supported at the scale and speed required. The research reported in this paper describes important lessons for good practice in changing contexts to modify behaviours for a triple win for health, equity and environmental sustainability. Authors synthesised learning from qualitative, quantitative and cost benefit evaluations of 15 case studies conducted in 12 countries in Europe. The case studies address ways of living (green spaces and energy efficient housing), moving (active transport) and consuming (healthy and sustainable diets) that support the triple win. Ten lessons for good practice were identified. These include bringing a triple win mindset to policy and practice in planning interventions, with potential to improve environmental sustainability, health and equity at the same time. The lessons for good practice are intended to support governmental and non-governmental actors, practitioners and researchers planning to work across sectors to achieve mutual benefits for health and environmental sustainability and in particular to benefit poorer and more socio-economically disadvantaged groups.
